Built with high-pressure gearing and supplied with an optional +25 psi spring for race-specific COPO Camaro setups, it improves oil delivery without changing reservoir volume. It fits engines using a 7\/8-inch inlet screen and bolts in place of factory units for a straightforward replacement.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 10295 change oil pressure and flow on my LS engine?\u003c\/h3\u003e\n\u003cp\u003eThe 10295 raises oil system pressure while maintaining the factory volume rate, providing firmer oiling performance under load without reducing flow. Compared with the M295, this pump produces roughly a 10 psi higher pressure at comparable operating speeds, making it useful for engines that benefit from higher oil pressure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-pressure internal gear design for increased system PSI.\u003c\/li\u003e\n  \u003cli\u003eStandard-volume displacement to preserve factory oil flow.\u003c\/li\u003e\n  \u003cli\u003eApproximately +10 psi over M295 at similar RPMs.\u003c\/li\u003e\n  \u003cli\u003eOptional +25 psi spring included for specific high-pressure needs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the pump fit my LS engine and what mounting hardware does it use?\u003c\/h3\u003e\n\u003cp\u003eThe unit is engineered for GM LS-series wet-sump blocks and installs in the same location as the OEM internal pump.
